On Thursday, July 31, "America's Best Dance Crew" welcomes hip hop superstar Missy Elliott. The six-time Grammy Award winner will be premiering her dance routine to "Shake Your Pom Pom," a song from her new album "Block Party," with the top four remaining crews joining her onstage. After the opening number, Missy will kick back and enjoy the show alongside judges Shane Sparks, JC Chasez, and Lil' Mama.

For this week's challenge, the crews will be given a popular Missy Elliott tune to dance to. In addition, they will be asked to emulate a challenging piece of choreography from their assigned song's music video. Hi-Hat, Missy's choreographer and collaborator, will lend a helping hand to the crews offering tips and advice on how to add that "Misdemeanor" quality to their dance routines.

Since Missy is notorious for her groundbreaking videos and innovative choreography, it's no surprise that the crews were excited when I informed them about their surprise guest right before the Tuesday taping last week. SoReal Cru's Brian (aka Burna) did a double-take when I told him that he would not only get to meet Missy Elliott, but he would also get to perform with her. "Shut up!" he said. "That's sick! Missy Elliott is … Missy freakin' Elliott. I'd love to dance to 'Get Your Freak On.'"

Make sure you tune in on Thursday at 10pm 'cause this will be an AWESOME episode!
